Why convert a Cycle Analyst to HIGO connectors?

Before you get a standard Cycle Analyst V3, you need to decide which model CA3 you need:

the CA3-DP with the speed signal entering the CA3 via the main cable only

or the CA3-DPS with an external speed sensor hardwired to the CA3 board. Here the wire from the main cable is disconnected from the board and tucked back.

On both standard models all cables enter the housing through the rear housing half. The holes are larger than the cable diameter, and the cables are secured with a piece of hotmelt lined shrinking tube from inside the rear housing.

The cables except the programming cable and the power jack are terminated with JST-SM connectors, in one case a single cable is terminated with 4 JST-SM connectors, leaving its inner wires exposed. The programming socket lies open.

The housing halfs are joined with silicone paste, and the front cover glass is glued to the inside of the housing.

The naked housing screwheads allow for moisture to seep into the housing, even though there are O-rings between the CA's rear housing and its board.

In the first case, we call the model CA3-HIGO. In the second case, the model is the CA3-CX, with the C standing for Custom and the X (X standing for the Roman number 10) for the up to 10 HIGO panelmount connectors you can fit. This allows you to use the Cycle Analyst as a cable hub centrally mounted on your e-bike's handlebar.

If you go with the panelmount version CA3-CX, pre-wire the HIGO Mini-B panelmount connectors and fit them in place. If you don't use all 10 holes, seal the remaining holes with a silicone plug. Fit the main cable, secure it and pot it with epoxy.

That is because if there is an established standard for wiring JST-connectors to a CA3, there must also be a Standard for wiring HIGO connectors to a CA3 in order to make things work as a plug and play system:
